In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

We all like cheap items off eBay especially if they do cool and unusual things, sometimes we get so carried away by the price that we do not even realize that fact that we do not know anything about ...

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino and a breakout ...

We've all missed the buzzer and forgotten a load of laundry once or twice. While setting an alarm is easy enough, but this Arduino-powered alert system will just send you a text when it's time to grab ...
